To all 'whom it may concern.' l Be it known that IJoHN-,Rrrsu, a' subject of the King'o'f Norway,.residing at Doylestown, in the county of Wayne and State of Ohio, have invented certain new' and use- @ful Improvements in AirCleaners, of which the following .is a specication. o. Y This invention relates to.; air cleaners.4 As is well known, a great deal of carbureter and engine` trouble is caused'v as the result of dust lladen air passing into such `To, overcome the o injurious results voccasioned by foreign particles, such as dust, in the car-bureter and engine cylinder various devices have been made for extracting ydust fromthe air prior to the time it enters theV carbureter. Y

It is the object ofimy present invention to provide a novel, inexpensiveY and eilicient air cleaner which may be readilyassembled and taken apart and which vis adapted "to meet all the requirements of the particular use.

The invention is illustrated on theaccompanying sheetsof drawings, in which:

showing more "clearly the pointed lopenings therein.- i p y The 4various novel features of rvmy `inven- Ation will be lapparenttfrom the following claims.

My air cleaner is of thewater type 1nV description andfdrawings and will be particularly pointed out` in the Vappended which'air to 4be cleaned passes through the water in the form of bubbles, the theory of operation being vthat the bubbles are graduallyreduced in size-:as a result of'vfrictional engagement with baiile plates or delectors, vcausing the'air to give up the dust carried thereby, this action being increased 1 by pointed or V-shaped openings in the baffle plates or delectors, theairV bubbles tendupper end lof the tube 13 being sealed by a plate 14=-whereby the'air, after passing upwardly through l the pipe 12, is directed downwardly in the tube 13 from which it passes through taperedlopenings 15 arranged circurnferentiallyv at the bottom thereon,

Secured to the tube v13 Vnear the bottom thereof is an annular bracket 16 which supports a conical baflie or air deflector 17, the outer edge of the baffle bearing against the casing 10. Mounted over and resting upon Y the outer edge ofthe baiile 17 is another bafle 18, the inner edge of which rests against the tube 13. Similarly battles 19, 20 and 21 are l,in turn superimposed one upon the other. plates or deflectors 17, 19vand 21 apluralityV of spaced circumferentially arranged,Y

cornered or V-shaped openings are provided, said openings preferably being formed by strikingthe materialdownwardly ina manner such that part ofthe struck down' material is on each side of the opening, the openings 22being pointed at their'finner ends and gradually increasing in size toward Near the outer periphery of baille their outer ends. Similarly/.plates or-deflec 1 A tors 18: and 20 near their inner edges are provided witha plurality `of spacedcircumferentially arranged V-shaped orepointed openings 23, the openings being larger. at

their .inner edges than at the outer edges.'

These baffles l17 to y21 are-submerged in water which may be passedinto the vcasing through a-water filler 24, the'height ofthe water in the lcasing being indicated by a gage 25. A cover 26 fits over the upper end of the casing 10 and Vis secured thereto by a plurality of anysuitable fastening members 27, said cover having a conduit 28 for the passage of purified air which'will be directed to a carbureteror othersuitablev devices not shown. To prevent rattling between the cover and the casing a cushioning ring 31 is interposed therebetween. Secured to the underside of the 'cover 26 are springs 29 and '30 which yeldngly bear.

upon the upper baille or plat-ev for holding all of the baffles or deflectors' in position.

of the casing, said cloth beinglr'et'ained in a spread out condition by a Weighted ring 35 "seated inthe bottom ofthe clotlrsack 32. v

1n operation the air is sucked-into and through the air cleaner byA the suction of .the engine.

A large part ofthe dust is removed from the air as the latter 1s drawn rinwardly through the ycloth '32, the air thus .drawn 'into .the `casing containing some dust 'in'g in 'the form` ef bubblesradiallyl out- -\vardly 'through the oblong openings 15 in the lower end of tube 13 out into the main f part ofthefcasing .10, A certain lamount of -the dust will igravitate inpassing rintothe 25' Water and will be deposited in the bottom of the 'casing'. The air bubbles naturally Will assume the lhighest possible position in any compartment. The'-air bubbles in passing :outwardly 'through'the oblong openings 15V pa'ss .into compartment 36,' the air bubbles immediately-rising Aand passing into engagement with' the flower surface of vthe baffile 'l plate 17 W'hereuipo'n 'the air bubbles will roll outwardlyal'ongthe'Linder side of the member 17. and fas-a lr'esult of the friction thus created between the .air' 'bubbles yand the member 11'? the air Vbubbles will be reduced be :separated 'from the air, whereupon it gravita't'es to the ibo'ttomfof the casi-ngv k10.
